I didn't have any trouble on this game on hardcore until the last couple of missions. I thought the achievement guide was great but for the author to say he only died twice for the entire game is nuts. I'm no gamer pro but I hold my own and there were a couple of checkpoints that took me 10+ tries alone. IMO, the author of the achievement guide on this site is either a gaming god or is full of shit. I just kept going and stating focused and finished the main story in about 6 or 7 hours. Don't quit, just hijack a UFO, shoot the shields off of a couple of the shielded UFOs, ditch the UFP you are flying, hijack another UFO, rinse and repeat.
